PTFE daim kab xev hauv PV Manufacturing: Los ntawm Lamination Consumable mus rau 25-Xyoo Rwb thaiv tsev

Taug kev mus rau txhua lub hnub ci vaj huam sib luag Hoobkas. Lub laminator khiav ntawm 150 ° C, nias EVA encapsulant ntawm iav thiab backsheet. Yog tsis muaj PTFE daim kab xev, molten EVA yuav ooze mus rau lub tshav kub platen thiab silicone diaphragm, tsim ib tug nplaum nplaum uas ua rau lub vaj huam sib luag tom ntej thiab yuav siv sij hawm sij hawm los khawb tawm.

Qhov ntawd yog qhov pom tseeb siv. Tab sis muaj qhov pom tsawg dua: hauv qhov ua tiav module, PTFE daim kab xev qhwv nyob ib ncig ntawm busbars qhov twg lawv dhau los ntawm backsheet qhib, tiv thaiv high-voltage creepage. Rau 1500V tshuab (tus qauv niaj hnub no), qhov rwb thaiv tsev no yog qhov yuav tsum muaj kev nyab xeeb.

Aokai PTFE muab ob hom - cov txheej txheem consumables thiab ruaj nrees rwb thaiv tsev - nrog rau cov kev xav tau sib txawv. Cia peb taug kev los ntawm qhov twg PTFE daim kab xev mus rau hauv PV module, thiab cov khoom twg tseem ceeb rau txhua qhov chaw.

Qhov twg PTFE daim kab xev siv nyob rau hauv Solar Module Production

Tsis yog ib daim ntawv thov - tsib.

Laminator Edge Protection - Sib ntaus EVA Stickiness

Thaum lub sij hawm lamination (145-165 ° C, 15-25 feeb), EVA encapsulant melts thiab ntws. Qee qhov inevitably nyem tawm mus rau ntawm ntug. Yog hais tias nws hu rau cov hlau cua sov phaj los yog silicone nqus diaphragm, nws bonds mus tas li.

1. Yuav ua li cas PTFE daim kab xev daws nws

PTFE daim kab xev siv rau cov chaw no ua rau kho EVA tev tawm hauv ib thooj. Cov neeg khiav dej num so daim kab xev nrog ib daim ntaub ntawm lub voj voog, thiab ib daim ntawv thov yuav siv sij hawm ntau lub lis piam.

2. Dab tsi los nrhiav hauv daim kab xev lamination

• Substrate: Fiberglass-reinforced PTFE (0.13-0.18mm). Ntshiab PTFE zaj duab xis kua muag yooj yim heev thaum khawb tawm kho EVA.

• Adhesive: Silicone PSA nkaus xwb. Acrylic softens thiab oozes ntawm 150 ° C, paug lub laminator.

• Thaum tshav kub kub shrinkage: Tsis pom zoo ntawm lamination kub - daim kab xev yuav tsum tsis txhob curl los yog nthuav tawm cov npoo hlau.

• Tsawg outgassing: Nyob rau hauv lub tshuab nqus tsev lamination, volatiles los ntawm cov nplaum tsis zoo tuaj yeem ua npuas hauv lub module. Tag nrho pawg poob <1% yog lub hom phiaj zoo.

Los ntawm lub Hoobkas hauv pem teb : Ib tus tsim qauv qhia txog kev txo cov laminator tu lub sijhawm poob qis los ntawm 45 feeb ntawm ib qho kev hloov mus rau 5 feeb tom qab hloov mus rau tus hwm fiberglass-rov qab PTFE daim kab xev nrog high-crosslink silicone nplaum. Daim kab xev raug nqi ntau dua ua ntej tab sis them rau nws tus kheej hauv ob lub lis piam.

Kev Ruaj Ntseg Busbar Kev Ruaj Ntseg - 25-Xyoo Kev Ntseeg Yuav Tsum Tau

Nyob rau hauv lub tiav lawm module, busbars (tinned tooj liab ribbon) txuas xov tooj ntawm tes rau lub hlws ris box. Qhov twg lawv dhau los ntawm ib txoj hlua khi hauv qab, los yog khoov ze ntawm lub thav duab aluminium, lub rwb thaiv tsev clearance yuav nruj. PTFE daim kab xev qhwv ib ncig ntawm lub busbar ntawm cov ntsiab lus no.

Daim kab xev no tsis yog khoom siv . Nws yuav tsum kav lub module lub warranty lub neej - 25 xyoo los yog ntau tshaj - sab nraum zoov, nyob rau hauv UV, kub cycling (-40 ° C rau +85 ° C), thiab damp cua sov (85 ° C / 85% RH).

1. Cov ntsiab lus tseem ceeb rau busbar rwb thaiv tsev daim kab xev

Kev lag luam ceeb toom: Qee tus nqi qis module tsim siv polyimide (Kapton) daim kab xev rau busbar rwb thaiv tsev. Thaum polyimide muaj lub zog dielectric ntau dua, nws nqus dej noo thiab tuaj yeem poob cov khoom siv hluav taws xob hauv cov cua sov. PTFE tseem nyob ruaj khov. Rau 1500V modules, PTFE yog nce ntxiv.

Junction Box Fixation & rwb thaiv tsev

Hauv lub thawv sib txuas, lub busbar tails solder rau diode / davhlau ya nyob twg thaiv. PTFE daim kab xev ua haujlwm rau ob lub luag haujlwm: rwb thaiv tsev qhov chaw liab qab nyob ze, thiab kev kho kho tshuab - taping xov hlau los tiv thaiv kev co qaug zog.

Yog vim li cas nplaim retardancy yog yuav tsum tau

Lub thawv sib txuas yog qhov muaj peev xwm ignition yog tias lub bypass diode tsis luv. PTFE daim kab xev ntawm no yuav tsum muaj UL94 V-0 ntsuam xyuas. Tsis tas li ntawd, nws yuav tsum tswj cov cua kub tsis tu ncua ntawm lub diode (feem ntau 85-90 ° C) yam tsis muaj kev nkag los yog poob adhesion.

Nyias PTFE zaj duab xis daim kab xev (0.05-0.08mm) ua haujlwm zoo ntawm no vim nws qhwv nruj nreem nyob ntawm cov xov hlau thiab cov terminals.

Soldering Mask & Kev tiv thaiv ib ntus

Thaum lub sij hawm tabbing thiab stringing, flux thiab molten solder tuaj yeem splatter rau cov hlwb, ua rau kom zoo nkauj tsis xws luag lossis micro-cracks. PTFE daim kab xev ib ntus npog cov npoo ntawm tes los yog qhov chaw tsis siv.

Cov kev cai sib txawv - tsis xav tau kev laus mus ntev

Tsuas yog kub kub tsis kam (lub sij hawm luv luv rau 300 ° C + los ntawm cov hlau soldering), solder-repellent nto, thiab xoom residue tom qab tev. Txawm tias cov nplaum acrylic tuaj yeem ua haujlwm ntawm no vim qhov raug luv luv thiab qhov kub thiab txias - tab sis silicone muaj kev nyab xeeb dua rau cov cua sov tshaj 200 ° C.

Quick Selection Cheat Sheet

Kawg Takeaways

Ob hom PTFE daim kab xev sib txawv ua haujlwm rau PV kev lag luam.

• Cov txheej txheem consumables (laminator tiv thaiv, soldering mask): tsom rau cov uas tsis yog-stick, yooj yim tu, thiab luv luv tshav kub kuj.

• Rwb thaiv tsev nyob ruaj khov (busbar qhwv, hlws ris lub thawv): xav tau tag nrho IEC 61215 kev tsim nyog - damp kub, thermal cycling, UV, thiab shrinkage <1%.

Silicone PSA tsis tuaj yeem sib tham rau txhua daim kab xev uas yuav pom 150 ° C + lossis 25-xyoo sab nraum zoov lub neej.

Aokai PTFE muab ob pawg nrog cov ntaub ntawv xeem. Rau busbar rwb thaiv tsev, peb muab damp tshav kub hnub nyoog dielectric zog cov ntaub ntawv. Rau lamination daim kab xev, peb muab kev soj ntsuam outgassing thiab teb lub neej ua pov thawj.
